Q:What is carbon accumulation?
Generally refers to the polycarbonate, PC, is a kind of thermoplastic plastics, good transparency, good mechanical properties, surface hardness, common uses such as CD, plastic glasses, a fence, protective window, public places, vacuum cleaners, coffee machine, juicer barrel, refrigerator shelf, pure such as the bucket.
Q:What is the HS number for billet export?
Your specification 13*13*6 or 12 meters, this is a square cross section, so 7207120000 this can not be used, your billet carbon content is 0.17 to 0.23% less than 0.25%, so we must use the following7207190000 Other Billets with carbon content less than 0.25%Export tax refund: 0%MFN country of import tariff: 2%General customs duties: 11%Export tariff rate: 0%VAT: 17%
Q:What is the drop per minute of the billet temperature at 850?
Cold rolling is not considered. The initial rolling temperature (surface) of the billet is generally 1000-1150 degrees. Generally, the temperature decreases gradually during the rolling process (a small section of high speed wire has a temperature rising process), usually above 750 degrees
Q:How can carbon and carbon in a fishing rod be distinguished?
Carbon fishing rod is divided into: carbon, pure carbon, high carbon.Carbon packaging, as the name suggests, two layers of material, the outside is a layer of carbon cloth, the inside layer is glass fiber, epoxy cloth. This kind of pole price is lower, this kind of pole does not recommend the brand, because the price is low, does not need to buy the brand. With a few times you can change, for beginners.Pure carbon refers to the overall use of 30T carbon cloth below the production of fishing rod, general 24T, 30T based, carbon content of more than 98%. The price is moderate, the fishing rod is recommended in the field of Koi, Koi a large proportion of domestic brands is unmatched, good quality.High carbon refers to the overall use of 30T carbon cloth above the fishing rod, but not the whole fishing rod is made of a carbon cloth.
Q:What is the difference between carbon three plants and carbon four plants?
The mesophyll cells of carbon three plants are more dispersed, and there are no chloroplasts in bundle sheath cells. Photosynthesis is only carbon three cycle, and the utilization rate of carbon dioxide is low. It usually lives in temperate zone.Four carbon plant mesophyll cells arranged regularly, the formation of two circles of the "ring" and bundle sheath cells, bundle sheath cells have no chloroplast grana, photosynthesis has three carbon cycle and carbon cycle four, higher utilization rate of carbon dioxide, the general life in tropical and subtropical regions.The initial product of CO2 assimilation is not photosynthetic carbon cycle in three carbon compounds 3- phosphoglycerate, but four carbon compounds malic acid or aspartic acid plant.
Q:What are the causes of internal cracks in continuous casting billet?
A French Research Institute of carbon, sulfur and phosphorus influence on continuous casting billet hot cracking, a total of three test groups of carbon manganese steel, carbon, sulfur and phosphorus content of each sample is different.
Q:What is the difference between continuous casting billet and cast billet?
Mainly to see the process, general casting efficiency is low, but the quality is acceptable, with low level (open casting billet) has great advantages in surface quality; but with high-grade continuous casting line (full protection casting, electromagnetic stirring, liquid stopper control) compared both have a big difference in the crystal, oxidation, surface quality.
Q:How to calculate the cost price of billet?
The ratio of slag to billet (63% fine powder) is about 3:1, which accounts for about 60%. of billet cost
Q:How does billet caster pull out billet cracking?
There are many kinds of cracks. Which one are you talking about? It is related to the water radian of the crystallizer.
Q:The reason for the blowhole in the billet to be pulled out by the continuous casting machine is 100
Production: 1 steel and 2 steel alloy or damp; for ladle lining refractory and no baking; otherwise the whole section are 3 billet bubble deposit if the situation is steel quality problems and the main problems of alloy billet; if the bubble is mainly between now and the relationship between process equipment (including continuous casting are clearly some problems of continuous casting machine the parameters of a)
